    February Sky & Tel article on extreme northern galaxies

    For another observing project I have an article in the upcoming February issue of Sky & Telescope on galaxies within 5 of the north celestial pole. Here's the first and last page, showing a table of galaxies discussed in the article.

    Interesting to see that the majority of the galaxies lie between RA 7h and 9h. I guess that's due to absorption in the Milky Way.


    Clear skies.

    It's an interesting group. I've only seen NGC 3172, J. Herschel's Polarissima Borealis.

    Most galaxies in this region are part of the NGC 2276 group (also known as LGG 145). The redshift-based distance is ~100 million l.y.

    You should give it a try Ivan it's a fun quest.

    Good suggestion Steve in showing people there is more to be observed around the N Pole than people think. 4 years ago I did this with my 12.5" going as far south as 80 N. Over 5 nights I managed 50 galaxies although the last night was only needed to gather in the final 3. It was tough and like you suggest took a very detailed chart I cobbled together from Megastar. Many of the tiny faint ones took magnifications up to 500X.

    These are the galaxies I observed.

    Bill, excellent results with your 12.5"! Like you I used Megastar charts to chase down the toughies. I didn't feel comfortable, though, "endorsing" Megastar in the article its hard to recommend purchasing a program that's basically unsupported and will likely have no future updating.

    Thanks Steve for sharing this. I am in Kiruna, Sweden, will try to see them.

    Clear Skies.
